"This research has three goals. The first goal is to develop a software interface (supervisor) to support and control a variety of interactive subsystem modules; thus eliminating manual scheduling of interactive jobs. The second goal is to develop a common methodology for interactive subsystem design. The third goal is to develop a linear systems analysis package using the facilities developed under the first two goals. A software interface (supervisor) to support and control a variety of interactive subsystem modules is described. The supervisor operates under the constraints of a large multiprogramming variable task operating system as opposed to a time sharing system. The supervisor not only eliminates the manual scheduling of interactive jobs, but also provides interactive users with a powerful dynamic linking mechanism. The supervisor permits the access of disk stored interactive modules in a random fashion. A methodology for developing interactive subsystems is presented. The problems of communicating between different high level languages are investigated and solutions are presented. In particular, a problem oriented language, interactive translator, is implemented using PL/1. The graphics service routines for this translator are coded in FORTRAN and ASSEMBLER languages. The techniques for adding graphics routines to existing programs, especially simulation languages, are formalized. A computer aided design program to assist in the initial phases of linear systems design is described. This program, developed for use at an on-line graphics terminal, allows the designer to describe a linear system in standard control engineering terms, and experiment with design alternatives during initial creative design phases"--Abstract, pages ii-iii.
